中海油美洲深水油气田开发技术现状与研究进展

Status and Progress of CNOOC Development Technologies in American Deepwater Oil&Gas Fields

美洲深水油气田已成为世界石油行业的热点之一,然而受水深影响,勘探开发面临巨大挑战。中海油公司(简称中海油)自2013年进入巴西2000m深水油气领域以来,逐渐形成了特色的超深水油气田评价井部署决策技术、延长测试部署与设计技术、深水巨厚碳酸盐岩储层非均质性精细表征与方案优化技术,应用于L油田并成功实现首次采油。中海油建立了海外油气田开发类比大数据平台,为1500m至2000m深水巴西C&V油田、墨西哥1&4油田的成功并购提供了技术保证。

American deepwater oil&gas fields have aroused world-wide interests in recent years.However,there have been huge exploration and development challenges due to great water depth.Ever since CNOOC entered 2,000 meter deep-water area in 2013,a series of technologies have been developed,including decision making technology for appraisal wells in ultra-deep water fields,deployment and design technology of extended well tests,and reservoir heterogeneity characterization and optimization of development plans for deep-water super-thick carbonate reservoirs,which leads to first oil fast in the L field.Based on the big data analogy platform in overseas oil&gas field development,CNOOC have succeeded in M&A of C&V fields in Brazil and 1&4 blocks in Mexico,which are all under water depth of 1500~2000 meters.
